I'm not seeing the problem that Frank is seeing at all.

4646 Registry:

    Type: grandfathered
    Tag: i-hak
    Description: Hakka
    Added: 1999-01-31
    Preferred-Value: zh-hakka
    Deprecated: 2000-01-10

    Type: grandfathered
    Tag: zh-hakka
    Description: Hakka
    Added: 1999-12-18

The grandfathered tag "i-hak" is deprecated in favor of the 
grandfathered tag "zh-hakka".

4646bis Registry:

    Type: grandfathered
    Tag: i-hak
    Description: Hakka
    Added: 1999-01-31
    Preferred-Value: zh-hakka
    Deprecated: 2000-01-10

    Type: grandfathered
    Tag: zh-hakka
    Description: Hakka
    Added: 1999-12-18
    Preferred-Value: zh-hak
    Deprecated: 2007-01-01
    Comments: replaced by ISO code hak

    Type: extlang
    Subtag: hak
    Description: Chinese, Hakka
    Added: 2007-01-01
    Prefix: zh

The grandfathered tag "i-hak" is deprecated in favor of the 
grandfathered tag "zh-hakka", which in turn is deprecated by the 
generative tag "zh-hak", composed of subtags "zh" and "hak".

What is irregular or ill-advised about this?

4646 Registry:

    Type: grandfathered
    Tag: zh-guoyu
    Description: Mandarin or Standard Chinese
    Added: 1999-12-18
    Preferred-Value: zh-cmn
    Deprecated: 2005-07-15

    Type: grandfathered
    Tag: zh-cmn
    Description: Mandarin Chinese
    Added: 2005-07-15

The grandfathered tag "zh-guoyu" is deprecated in favor of the 
grandfathered tag "zh-cmn".

4646bis Registry:

    Type: grandfathered
    Tag: zh-guoyu
    Description: Mandarin or Standard Chinese
    Added: 1999-12-18
    Preferred-Value: zh-cmn
    Deprecated: 2005-07-15
    Comments: replaced by ISO code cmn

    Type: extlang
    Subtag: cmn
    Description: Chinese, Mandarin
    Added: 2007-01-01
    Prefix: zh

    Type: redundant
    Tag: zh-cmn
    Description: Mandarin Chinese
    Added: 2005-07-15

The grandfathered tag "zh-guoyu" is deprecated in favor of the 
generative tag "zh-cmn", composed of subtags "zh" and "cmn". 
Coincidentally, there is also a redundant tag "zh-cmn" which is 
syntactically and semantically identical to the generative tag "zh-cmn".

What is irregular or ill-advised about this?
